'.Kansas City. the county of 'Wyandotte and State ot Kansas, have invented certain new and useful improvements1n Silos; and

l do declare the iilloning to he-a ulh.

clear, and exact deseription ot the invention. sueh as will enable others skilled in the` art to which il appertains to 1nalte` and use the saine` reference being had to the accompanying drawings, and to the letters and figures ot' reterenee marked thereon, which 'form a part of this specification.

My invention relates to silos, and more particularly to a silo constructed of sheet metal, the principal object oi? the invention being to provide a strueture ot this character which nia)1 be erected at a reasonable initial eost and ivill be more perinai'ient and satisfactory than strhetures of this kind composed oi n'ood or concrete. In aecomplishing this object. l have provided the improved details ot' structure hereinafter described and illustrated in the accompanying drawings, wherein Figure l is a side elevation onta silo constructed according to my invention` showing a door opening` partly closed. Fig. ll is an enlarged sectional view of the concrete base and part of the metal shell. Fig. lll is a perspective vie'iv of the base flange ivith one oli the shell plates in position7 showing the. preterred method of starting the erection of the plates. Fig. iV is an enlarged perspective view ot one ot the plates. Figi'. V is a similar view of superimposed plates showing the method of and lower` plates. Fig. Vl is a perspective view of the cap trame. Fig. VII is an inside perspective view ot part of thel door trame and one of the doors, a section of the door being breiten sway to show the gasket.

Referring more 1n 1 designates the heseoi the silo` which 1s detail to the parts constructed-'of Concrete and has a eireumferential groove' 2 in the top for reeeivingfthe hase ot the shell. Seated in the groove Q is a circular angle iron 3 which is held' in place by angle hooks i that are embedded in the concrete base While the latter is being formed. The angle member 3 extends en'- irely around the base but yis cnt at a door position to provide recesses Seated on the angle member 3 is the first tier of shell pistes i3, the ends oit which are riveted together to torni a solid collar except for a door opening 7, which rises Yfrom the hase above ih/sangle slots 5, the plates having their ends terminating at the door positioinl and being provided with lips 8 which extend haelt into the body of the structure to form Jhe door jambs. On the upper edge oi' each oi plates G is an inlurned shoulder t) having an upturned flange l0 foji'nine` a seat and'baek -for the loiver edge of a shell plate in an upper tier. The plates in the upper tier are seated on the. shoulders 9 of the plates in the lower tier and riveted to the back flange 10 to torni an integral structure. l prefer to place i'iber or like packing ll between the lower edges ot the plates in the upper tier and the baci; iianges 10 of the plates inthe lower tier and between the overlapping ends ot the plates in the same tier in order to assist. in making the siriietnre air and moisture proof. Succeeding tiers are formed in the same Wav until the silo has been erected to a desired height..

After the shell plates have been erected, the door-frame is applied thereto, snch frame consisting of angle members and spacers which are arrz nged and combined in the following manner: At the inside of the structure an angle iron 12' is raised against each of the janib iianges 8 0i the angle platesggind seated in the groove formed by the flange and bodT of the plate; An angle bei 13 is then raised against the outer face of said iam'b plate and fitted over the angle formed by the things shell plate te bind the tienges and adjacent portion of the. plates between saine and inner bar l2. Prior to the erection of the shell and jamb members, the-se parts havehad bolt holes lll-formed in the angles thereof so that when the parts are assembled, as described, bolts l5 meg: be projected through the holes 8 and outer face oi the angle iron and nuts 18 applied to the thread of the door opening) in order to coperate so that the bolt heads 16 )vill nest in the groove of the inner angle iron iVashcrs 17'are'then fitted over the corner ofthe outer would not be held in place after the ensilage is removed. In order toclose the door from Without, I rovide a fastening comprising a double-han ed lever 3l which is pivotally 70 mounted at its center on a pin 32 that is carried on a vertical cleat 33 on the front of. the door.

Pivotally connected with an intermediate bar 34 of the lever at each end thereof is a 76 pressure bar 35 which extends throu h a racket36 on a cleat 3l' on the side o? the ed Shanks of the bolts and tightened against the heads of the V-shaped washer to tighten same against the outer angle iron and draw the arts snugly together.

en both of the door jambs have been erected, cross-bars 19 may be inserted to space the jambs apart, said cross-bars being spaced at regular intervals throughout the height with the door mem ers. I also prefer to adjacent door-Jamb, the beveled under face ing the bars 19 in p ace.

21 designates the top of the silo, which may o any suitable construction, but preferably provided with a manhole 22 through which ensilage may be delivered to v t e interior of the silo. the oors may be installed as they are needsit is important to kee moisture out of ed, and that when the ensilage-is removed the silo, a door especially a apted for tightly from the top the doors may be taken down ladder rungs 39 on the outer faces of the 85 doors 'whereby a erson may climbv to the top of the doors when the opening is closed.

t is apparent that after the shell is erected closlng the oor opening is provided. This to keep the upper door level on a level with the `top of' the ensila e so that ready access w ich are fixed to one of the inner door to the latter is afforfed.

jamb members and comprise cylindrical It as been found that with a sheet metal members 24 which are projected into the structure like the-one herein described the shell structure past the inner edges of the common disadvantage of the expansion and jambs, the hinge members being arranged in pairs at each door position. A door 25 is provided for cach door position on the frame and adapted to fit snuglyagainst the inner like, which, with silos constructed of other edges of the jambs. The doors are prefermaterial. must be constantly cared for, -in

nection`5 and hung by hinge members 26 hav- 'falling apart when the silo is empty an the 105 i g straps 27 extending over the edge theicshell dried by summer heat.

of and provided-With elongated pin slots 28, It has also been found that by painting the e ges'of the straps being bent back to the interior of the shell with a re eration a ut against the part of the strap body l prepared for that purpose, the s el is ro- Vand may also move toward and from the 65 ensilage will not pack su iciently to insure y tected from acids or moisture of the ensi age slots 28 and through the cylindrical members 24 of the frame hinge members 23, the of the ensilage to hold on account of conupper end of the rod bein turned laterally tactinga moist shell is obviated. to form a hook that will eep the same in I `aving thus described m invention, what place and prevent its falling through the f dydesre to secure inges. It is apparent that With a inge of this kind the door may pivot on its hinge x si o comprising a shell formed of sheet metal and having a vertical o ening door opening, so that as the ensilage settles ll therein, the sheet metal having anges in thesilo the pressure will tend to force the I' turned inwardly at the sides of the opening, oors into close contact With the jambs. door jambs connected with said iianges, said i i gambs comprising inner and outer angle ture and air proof, I prefer to `line the jambs irons, having their flanges lying against the and crossbars 19 with strips 30 of suitable angle portions of the sheet metal and means @25 packing which will insure the moisture and for securing said door jambs to said shell. air roofing of the door connection. l.. i siloy comprising a shell formed of yhile the contents of the 'silo Will tend r sheet metal and having a vertical opening to force the door to a ti ht closure, fresh therein, the sheet metal having Hanges turned .inwardly at the sides of the opening,

' door jambs conneotefi with said flanges, said i jlnbs comprising inner and outer angle irons, having their flanges lying against the 4:Lingl'efportions ofthe sheet metal, and bolts 1 extending through the vertices of the angles of the shell and the angle irons to bind the p arts' together.
